The alarmingly threatened Aquatic warbler: from early ecological insights to current conservation priorities

open access: yesRestoration Ecology, EarlyView.
The Aquatic warbler (Acrocephalus paludicola) is the rarest songbird of continental Europe and a fen mire specialist. The systematic drainage in the eighteenth and nineteenth centuries resulted in the loss of almost all fen mires in the breeding range. In our conservative and cautious estimate, we assume that the total historical population was around ...

Dynamics of a prey-predator system under the influence of the Allee effect and Holling type-II functional response [PDF]

open access: yesNetwork Biology
Capturing complicated dynamics and understanding the underlying controlling ecological processes is one of the major ecological issues. The Allee effect is an essential component in ecology, and considering it can have a substantial impact on system ...

Management of invasive Allee species

open access: yesLetters in Biomathematics, 2017
In this study, we use a discrete, two-patch population model of an Allee species to examine different methods in managing invasions. We first analytically examine the model to show the presence of the strong Allee effect, and then we numerically explore ...

The Goldilocks Effect: How the “Just Right” Writing Styles of Global Corporate Responsibility Frameworks Shapes Their Use by Businesses

open access: yesRegulation &Governance, EarlyView.
ABSTRACT The 21st century has witnessed a surge in the number of global corporate responsibility (GCR) frameworks issued by international organizations (IOs). Our study investigates whether and to what extent these frameworks shape businesses' Corporate Social Responsibility (CSR) communications.

Complex Dynamics of a Diffusive Holling-Tanner Predator-Prey Model with the Allee Effect

open access: yesAbstract and Applied Analysis, 2013
We investigate the complex dynamics of a diffusive Holling-Tanner predation model with the Allee effect on prey analytically and numerically. We examine the existence of the positive equilibria and the related dynamical behaviors of the model and find ...

T(w)o Patch or Not T(w)o Patch: A Novel Biocontrol Model

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 13, Page 14697-14743, 15 September 2026.
ABSTRACT A number of top‐down biocontrol models have been proposed where the introduced predators' efficacy is enhanced via the provision of additional food (AF). However, if the predator has a pest‐dependent monotone functional response, pest extinction is unattainable. In the current manuscript, we propose a model where a predator with pest‐dependent

Dynamic Analysis of an Amensalism Model Driven by Multiple Factors: The Interwoven Impacts of Refuge, the Fear Effect, and the Allee Effect

open access: yesAxioms
This paper investigates a model of amensalism, in which the first species is influenced by the combined effects of refuge and fear, while the second species exhibits an additive Allee effect.

From Cohesion to Norms: How Animal Groups Come, Stay, and Function Together

open access: yesEthology, Volume 132, Issue 9, Page 604-622, September 2026.
The present review underscores two salient points: In the context of evolutionary transitions to pair‐ and group living, it is imperative to acknowledge the distinction between selective forces that act during the origin of these social systems and those that act during their subsequent maintenance.
